“Selecting award-winning bridges in the 2018 competition was more challenging than ever,” said Michael Culmo, PE, CME Engineering, the lead judge in the competition. “Submissions came from all across the country, including Hawaii and Alaska, and represented numerous structure types, construction methods and project delivery models. Our recognized bridges included bridges that extended the boundaries of steel design and steel bridge construction, and others that showed efficient use of steel as a material of choice for bridges.”

Winning projects were selected based on innovation, aesthetics, economy, and design and engineering solutions by a jury of five engineering and construction professionals: Michael Culmo, PE, CME Engineering; Frank Russo, PE, PhD, Michael Baker International; Amber Blanchard, PE, Minnesota Department of Transportation; Tony Hunley, PE, PhD, Stantec; and Dominique Shannon, PE, Kansas Department of Transportation.
